Base44 vs Lovable: Which AI App Builder Should You Use?

Base44 and Lovable are both AI app builders that generate a working full-stack application from a prompt, but the database underneath is a real structural difference: Base44 runs on its own NoSQL store with no documented way to swap in an external database, while Lovable can run on its own managed backend or connect to a Supabase project you control. Both export real code you can host elsewhere. Here's what each vendor's own documentation says about how they build, what you own, what hosting looks like, what the credits actually pay for, and who each isn't for.

How do they compare at a glance?

How does each one actually build an app?

Base44's own quick-start guide describes the process directly: "Base44 is an AI-powered website and app builder. You do not need any coding or tech skills. Just describe what you want to build, and Base44 will bring your idea to life" (Base44 docs, "Building an app", checked September 2026). Base44 states it handles "design, databases, signups, user permissions, and hosting" automatically, and the result is "instantly live and shareable" (same source). Under the hood, an app's data model is built from entities — Base44's docs describe an entity as a schema "stored in Base44's NoSQL database," adding "the database is MongoDB-compatible, so you can use MongoDB operators when querying through the SDK," and that "you can update your data model at any point without running migrations" (Base44 docs, "Entities Overview", checked September 2026).

Lovable's documentation describes itself as "a full-stack AI development platform for building, iterating on, and deploying web applications using natural language, with real code, security, and enterprise governance," stating that it "generates a working application that includes frontend, backend, database, authentication, and integrations, all backed by editable code" (Lovable Documentation, "Welcome", checked September 2026). Its own Cloud backend "utilizes Supabase's open-source foundation, which means you get a production-ready environment from day one, without needing to set up Supabase separately" (Lovable Documentation, "Lovable Cloud", checked September 2026) — Supabase's database is Postgres, relational rather than document-based.

What's the real difference in database choice?

Lovable documents a second backend path beyond Cloud: the Supabase integration, which "connects a Supabase project you own to your Lovable project and uses it as your app's backend." Disconnecting stops Lovable from deploying to it, but Lovable says it "does not change your code and does not delete anything in your Supabase project" (Lovable Documentation, "Connect to Supabase", checked September 2026). Either Lovable path ends on Postgres, with the option to own the database account directly, outside Lovable.

Base44's documentation describes only its own built-in NoSQL entity store; it doesn't describe a way to connect an external database such as Postgres or a self-hosted MongoDB instance. If your app needs relational joins across many tables, or you specifically want to own a separate, provider-agnostic database account from day one, that's a real limitation to weigh — not a feature gap you can route around inside Base44 today.

What do I actually own, and how do I get the code out?

Both vendors document a real code export, gated to a paid tier. Base44's docs state plainly: "Downloading a ZIP file and connecting to GitHub both require a Builder plan or higher" (Base44 docs, "Developer tools", checked September 2026), and its GitHub sync is two-way but has a real limitation: "there's no option to manually push updates from your Base44 app to GitHub" — sync happens on Base44's own timing (Base44 docs, "GitHub Integration", checked September 2026). Our full guide to exporting a Base44 app covers the ZIP download, the GitHub sync mechanics, the plan gate, and what doesn't come with the export — read that instead of repeating the steps here.

Lovable's GitHub integration works differently: connecting a project "creates a new GitHub repository and starts two-way sync automatically," and the result is an ordinary GitHub repository you control (Lovable Documentation, "Sync your Lovable project with GitHub", checked September 2026). Lovable's own sync documentation doesn't state a plan requirement for this feature the way Base44's export documentation does; check Lovable's pricing page if you want to confirm which plan your account is on before relying on it. Our guide to moving a Lovable project to your own hosting covers the GitHub sync, deploying to Vercel or Netlify, and what happens to Supabase and your secrets when you leave — read that instead of repeating the steps here.

What does hosting and a custom domain look like on each?

Base44 hosts every app by default at a Base44-issued link, and a custom domain is a plan-gated add-on: "Custom domains are available on the Starter, Builder, Pro, and Elite plans" — not Free (Base44 docs, "Setting up your custom domain", checked September 2026). Base44 states it "issues and renews your SSL certificate automatically once your domain is connected" (same source), and documents a cap of "up to 150 domains and subdomains to a single app, and up to 350 domains in total across your account" (same source).

Lovable also hosts every app at a default lovable.app link, with custom domains gated similarly: "Custom domains are available on paid plans" (Lovable Documentation, "Custom domain", checked September 2026), set up with an A record to Lovable's edge IP and a _lovable-prefixed TXT record. The bigger difference is what happens after: Lovable's GitHub sync lets you deploy the same codebase to Vercel, Netlify, or another host entirely, while Base44's documentation describes hosting and domains as part of the Base44 platform itself, with no equivalent "deploy this codebase to a different host" path documented for the exported ZIP or synced repo.

How does each one's credit-based pricing actually work?

Both charge through credits rather than flat per-seat pricing. Base44's pricing page describes two credit types: message credits, its "monthly usage allowance for AI messages and integration actions," and integration credits for additional usage, scaling by plan from Free through Elite, and states "exact usage varies based on the action and the selected AI model" (Base44, pricing page, checked September 2026). Check Base44's pricing page for current plan names, prices, and credit allocations.

Lovable's pricing page defines one credit type: "Credits are units Lovable uses to measure and pay for usage across your workspace. Credits let you build apps, run deployed apps, and power AI features from one balance" (Lovable, pricing page, checked September 2026). Check Lovable's pricing page for current prices and allocations.

What does each do for SEO?

Base44's documentation describes real, automatic SEO handling for apps on a custom domain: it "automatically manages" core meta tags including "self-referencing canonical tags," "automatically generates and serves a sitemap at /sitemap.xml," and "automatically serves crawlers a rendered version of your pages" so that "AI crawlers and search engines can read your pages without executing JavaScript" (Base44 docs, "Getting your app found in search", checked September 2026). Base44's docs add a real caveat: these features are built for apps "published on a custom domain" — a free Base44-issued URL "can still be crawled by search engines, but they are not intended for long-term, production SEO" (same source).

Lovable's SEO story depends on when your app was created and involves more moving parts: pre-rendering served only to verified crawlers for older apps, full server-side rendering for apps created from May 13, 2026 onward, plus a sitemap and per-route metadata you're responsible for checking. Our guide to a Lovable site not showing on Google covers that full checklist in the order Google's own tools recommend checking it — read that rather than assuming Lovable's approach matches Base44's automatic handling described above.

Who is each one not for?

Base44 is not a fit if your data model needs relational joins across many linked tables, if you specifically want to own an external, provider-agnostic database account from day one,. Base44 also builds its SEO handling around a custom domain, so plan on one if search traffic matters.

Lovable is not a fit if you want a NoSQL, schema-flexible data model without setting up a relational database, or if the built-in backend-as-a-service simplicity Base44 offers (no separate Supabase project to configure at all) matters more to you than SQL and export flexibility.

Is Figment a fit for either kind of project?

No. Figment publishes designs from Figma as websites through a Figma plugin, and its AI editor is a preview with an access-request form, not a production tool. Neither Base44 nor Lovable's job — a prompt-generated, database-backed application — is what Figment does; Figment is a route to a marketing site or portfolio from a Figma design, not an app builder with a backend. If your Base44 or Lovable project's job is really a marketing site in front of the app, can AI edit my website covers the general question of what any AI tool can and can't change on a live site.

Which should I actually pick?

• Pick Base44 if you want the simplest path from a prompt to a hosted, working internal tool or small product, don't need relational data, and are comfortable with GitHub sync running automatically rather than on a manual push.
• Pick Lovable if you want a SQL/Postgres backend from the start, or want the option to own a completely independent Supabase project outside the builder.
• Check both vendors' current pricing pages before committing, since credit allocations and plan prices on both sides are set on pages that update independently of this guide.

Bottom line: the database choice is the real fork in this comparison — Base44's own NoSQL store with no documented external option, versus Lovable's Postgres-based Cloud or a Supabase project you can own outright. Both let you take the code out; Base44 gates that behind its Builder plan, and Lovable's GitHub docs don't state a plan gate.
